摘要:
【目的】针对目前陕西关中地区日光温室跨度结构不规范的现状,开展温室合理跨度筛选研究。【方法】以陕西关中地区普遍使用的跨度分别为8,9和10 m的日光温室为研究对象,以该地区的主栽番茄品种“金鹏1号”为观测作物,从环境数据和植株生长2方面分析不同跨度结构温室的光、温性能。【结果】3个不同跨度的温室中,10 m和9 m跨度温室的平均温度分别比8 m跨度温室高2.5和1.5 ℃,平均光照强度分别比8 m跨度温室高2.18和2.01 klx,平均空气相对湿度分别比8 m跨度温室低0.7%和3.3%。10 m跨度温室的采光性能和温度条件较好,室内番茄的产量较高,而9 m跨度温室的空气相对湿度较低,保温性能较好,室内番茄的果实品质较好,产量也较高。【结论】综合评价认为,9 m跨度温室更适合在陕西关中地区的番茄种植中优先推广应用。

Analysis of light and temperature conditions of sunlight greenhouses with different span lengths in Central Shaanxi Plain
Abstract:
【Objective】This experiment aimed to standardize the structure parameters of sunlight greenhouses in Central Shaanxi Plain,and select reasonable parameters of greenhouses in this area.【Method】Three greenhouses with span lengths of 8 m,9 m and 10 m were studied.The “Jinpeng One” was used as experimental plant.Temperature,humidity,light intensity,plant height,stem diameter,chlorophyll content and yield were recorded and analyzed.【Result】The temperature,light,and humidity conditions of greenhouses with span lengths of 10 m and 9 m were better than that of greenhouse with span length of 8 m.The average temperature and light intensity of greenhouse with span length of 10 m were 2.5 ℃ and 2.18 klx higher than that of 8 m,respectively,while its average relative humidity was lower than that of 8 m by 0.7%.The average temperature and light intensity of greenhouse with span length of 9 m were 1.5 ℃ and 2.01 klx higher than that of 8 m and its average relative humidity was 3.3% lower than that of 8 m.The light and temperature performances of greenhouse with span length of 10 m were better,while the thermal insulation and humidity performances of greenhouse with span length of 9 m were better.【Conclusion】The structure parameters of Sp9 and Sp10 were more reasonable than Sp8.On account of land utility rate,Sp9 was most suitable for extension and application in Central Shaanxi Plain.
